How would sale of Blockbusters affect stock?

[kham83]

I'm 27, and looking into start building a stock portfolio. A penny stock that Ive been looking into buying is Blockbusters. I know they are doing terrible, but I have reasons to believe that they can turn things around. Today I read that they are probably looking to put the company up for sale. I was wondering, how would the sale of Blockbusters affect its stock prices? What factors are there to consider? Is there a rule of thumb to "Not Buy" when a company is going to sell? Any info will be appreciated. Thanks
